30、etectors for installation in and around buildings. Multi-sensor detectors respond to a broad range of fires and can be designed to achieve high stability against deceptive phenomena that can result in unwanted alarms.A fire detection and alarm system is required to function satisfactorily not only i

31、n the event of fire, but also during and after exposure to conditions it is likely to meet in practice, including corrosion, vibration, direct impact, indirect shock and electromagnetic interference. Specific tests are intended to assess the performance of detectors under such conditions.This editio

32、n introduces a requirement that smoke sensors that operate on the principle of scattered or transmitted light to be marked with one of two possible nominal response threshold bands. The availability of two of response threshold bands provides installation designers with a detector selection choice t

33、o further reduce the risk of unwanted alarms in installations where unfavourable environmental conditions are present.This edition introduces additional requirements for smoke detectors with more than one smoke sensor.

34、ion and alarm systems Part 15: Point-type fire detectors using smoke and heat sensors1 ScopeThis part of ISO 7240 specifies requirements, test methods, and performance criteria for point-type fire detectors using smoke and heat sensors, incorporating in one mechanical enclosure at least one smoke se

35、nsor and at least one other sensor which responds to heat, and in which the signal(s) of the smoke sensor(s) is (are) combined with the signal(s) of the heat sensor(s).The performance of a single sensor within the detector covered by this part of ISO 7240 cannot be sufficient for conformity to other

36、 parts of ISO 7240 for the single sensor detector.Certain types of detectors can contain radioactive materials. The national requirements for radiation protection differ from country to country and they are not therefore specified in this standard. However, such detectors are expected to conform to

37、the national requirements and be in line with the recommendations of the Nuclear Energy Agency (NEA) of the Organization for Economic Co-operation and Development (OECD)1).For the testing of other types of detectors, or detectors working on different principles, this part of ISO 7240 can be used onl

38、y for guidance. Detectors with special characteristics, developed for specific risks, are not covered in this part of ISO 7240.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

46、 accordance with Clause 5 and shall meet the requirements of the tests.b) Clauses 7 and 8, which shall be verified by visual inspection.4.2 Design considerationsDetectors shall be so designed that the signal(s) from the smoke sensor(s), combined with the signal(s) from the heat sensor(s), release an

47、 alarm signal.NOTE In some cases, an alarm signal can result from only one element, but the overall fire performance is dependent on signals from more than one sensor being combined in some form of signal processing.4.3 Smoke-response value of detectors using scattered or transmitted lightDetectors

48、using scattered or transmitted light shall conform to one of the two response threshold value bands specified in Table 1 and the corresponding end-of-test conditions for the test fires specified in 5.22.Table 1 Smoke-response value for detectors using scattered or transmitted lightSmoke-response val
